67-541-INK 20.0mm Dia. x 150.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-541-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 20.0mm, is designed for use in the Near-Infrared II (NIR II) spectrum, specifically for wavelengths between 750 and 1550nm.
The lens features a front and back coating of edm nir-ii std curve, which is specifically designed for use in the NIR II spectrum. This coating enhances the lens' performance in this spectral range, providing improved transmission and reduced reflection.
The lens has a thickness of 1.59mm at the edge and 3.0mm at the center. The effective focal length (EFL) of the lens is 70mm, and the radius of curvature (R1) is 36.18mm. The back focal length (BFL) of the lens is 68.03mm, and the lens does not have an inner or outer radius.
The lens is made from n-bk7 schott, a common material for optical lenses due to its excellent optical properties and high Abbe number. This material ensures high transmission and low dispersion, making it ideal for use in the NIR II spectrum.
According to the vendor, the lens is currently in stock, and more information about the lens, including technical specifications and datasheets, can be found on the Edmund Optics website.
